Mostly however, when astake the device is associated withthe car illus- 3 3 trated in Figure 1, the admission of air into thecylinder in back of the piston causes the forward movement thereof. Thelatter action causes the straightening head 10 to be 5 brought intoengagement with the bent portion of the stake B so as to bring about thestraightening of the stake. The device is shown as being applied to acar of shallow depth.

When used in conjunction with a car of greater depth the-tie straps 13will be secured to the lower end of the frame beneath the cylinder. I

It will thus be seen that I have provided 15 a highly novel, simple, andeflicient coal car stake straightening device that is well adapt ed forall the purposes heretofore designated.

Even though I have herein shown and described the invention asconsisting of certain detail structural elements, it. is nevertheless tobe understood that minor changes may be made therein without affectingthe spirit and scope of the appended claims.

Having thus describechny invention, what I claim as new is:

1. -In a coal car stake straightening device, a frame unit, meansassociated with one end of the frame unit whereby to facilitate itsattachment to the upper edge of a wall of the car directly above theupper end of the stake to be straightened, means whereby the lower endof the frame may be secured in spaced relati0n-with the car, a cylinderassociated with the frame and having a rectilinearly movable pistontherein, a lever pivoted at one end to the forward end of the piston rodand at its opposite end to the said frame and a straightening headassociated 40, with said lever and adapted to be moved into engagementwith the bent portion of the stake when ressure is admitted into thecylinder in bac of said piston.

2. In a coal car stake straightening device,

an inverted L-shaped member having a finger on the lateral portionthereof for hooked engagement over the upper edgeof the car, above theupper end of the car stake, means pivotally disposed on the verticalportion of the L-shaped member having a finger thereon for engagementwith the lower part of said car, a lever ivoted at one endto the-lateralportion 0 said L-shaped member, a straightening head arranged on saidlever,

and power means associated with the other end of said lever for forcingsaid straightening head into engagement with the bent portion of saidstake.

\ In testimony whereof I aflix my signature. so CAREY E. STRAUSBAUGH.
